OATMEAL-MACHINE. 1

SPECIFICATION forming part of Letters Patent No. 363,875, dated May 31,1853. 7

Application filed July 30, 1886.

To aZZ whom it may concern:

Be it known that I, AMos W. WooDwARD, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Oatmeal-Machines, of which the following is a specification.

This invention relates to that class of ma-' chines wherein hulled oats and other cereal grains are cut transversely to theirlonger axes into grits by means of chisel-edged knives.

The object of this invention is to cut grain rapidly into grits without crushing or breaking it. r l

In the accompanying drawings, which form a part of this specification, Figure 1 represents an isometrical-view of my machine, partially broken away to show theinterior construction thereof. Fig. 2 represents a transverse vertical section of my machine through the dotted line m, Fig. 1. Fig. 3 represents an end view of the feed-cylinder of the machine. Fig. 4

. represents a longitudinal. partial section of a fragment of the feed-cylinder through the dotted line 00 a7, Fig.3. Figs. 5, 6, 7, 8, and 9 represent enlarged isometric views in detail of fragments of obvious portions of the machine; Fig. 10 represents a trausversesection through the dotted lines at of the parts shown by Figs. 5 to 9, inclusive, arranged in operative relation, with additional cross-sectioned adjacent parts. Consider the dotted lines 00' as all having laid in the same vertical plane at the time the section shown in Fig. 10 was made. Fig.

11 represents a section of Figs. 8 and 9 through the dotted lines :0

extending along and below the bottoms of the primary grooves, and the propelling-shoulders G. The journals'B and 0 are formed integrally with their cylinders 13' and O.

-D D represent casings partiallyin'cl'osing. I

ing grain downward into the primary grooves C ofthe feed-cylinder O.

'F represents a knife furnished with the transverse slots F and secured to the cylinj der-casing D by means of screws F F represents a set-screw for adj Listing-the knife F to the feed-cylinder O.

G represents a grain-guide provided with the teeth G.

G represents screws securing the grainguide to the casing D.

II represents a strong knife secured to the casing D by means of the screws H..

H represents a long narrow aperture extending between the grainguide G and knife H. I represents askeleton cutting-cylinder com posed of the circular disks 1 and the revolv- 4 ing cutting-knives 1 set into the peripheries thereof. The cutting-cylinder I is mounted upon the shaft 1 the latter having the bearings 1*, which are secured to the bed-piece A.

J represents a casing covering the front of the cutting-cylinder.

K represents screws, wlth their lower ends resting upon the upper surface of the bedpiece A, for regulating the distance between the knives I of the cutting-cylinder I and the grain-guide G.

K represents screws for securing the front of the frame-work to the bed-pieee A after. the screws K have been adjusted.

L L L represent pulleys-the two former, I

mounted upon shaft I and the two latter connected by a belt, L I

L represents a" shaft, whereon the pulley L y is mounted and revolves.

M M M represent gear-wheels meshing together and mounted upon the shafts L, B, and C, respectively. I

By removing the belt L and loosening the screws K, the frame-workAA and all the parts which it supports may be turned back, fully exposing the cutting-cylinder I to view.

The distributing cylinder B, operating in conjunction with the grooved plate E, distributes the grain to the primary grooves (l of the feed'cylinder O,whereupon the propelling shoulders G" propel the grain dow-nward until the teeth G of the grain-guide G intercept the kernels of moving'grain and guide them downward and forward out of the primary grooves C and discharge them lengthwise in single files through the opening H", to be out into grits by the joint operation of the knives H and I".

The sole function of the primary grooves (l is to receive kernels of grain y, as indicated in Fig. 10, and convey them to the teeth G of the grain guide G, which discharge them through the aperture H The only office of the secondary grooves O is to contain the teeth G of the grainguide G.

The office of the knife F is to break up all hard gritty substances, (they will invariably find their way in small quantities into the cleanest grain,) so as to allow their fragments to pass through the machine without eroding the inner surfaces of the casings D D or dulling the knives H and I.

I claim- 1. In an oatmeal-machine, a feed-cylinder having annular primary grooves in the periphery thereof, narrower annular secondary grooves extending alongand below the bottoms of the primary grooves, and shoulders proj ecting into the primary grooves for propelling kernels of grain to revolving cutting-knives, substantially as described.

2. The combinatiomin an oatmealmachine, with the feed-cylinder 0, having the primary grooves 0 secondary grooves 0 and propelling-shoulders O, of a grain-guide provided with teeth for intercepting. and conducting grain away from the primary grooves of said feed-cylinderto revolving cutting-knives, sub stantially as described.

3. The combination, in an oatmeal-machine, with the distributing-cylinder provided with the pins B of the grooved plate E, feed-cylinder O, casings D D, knife F, grain-guide G, knife H, and cutting-cylinder I, substantially as described, and for the purpose specified.
